MANNER OF MANUFACTURING BOOTS AND SHOES,

Specification of Letters Patent No. 2,062, dated April 24, 1841.

To all whom t may concern.'

Be it known that I, ANsEL THAYER, of Braintree, in the county of Norfolkand State of Massachusetts, have invented an Improvement in the Mannerof Making Boots and Shoes, which I denominate Metallic-Shank Boots andShoes; and I do hereby declare that the following is a full and exactdescription thereof.

In boots and shoes, as improved by me, there is not any outsole ofleather from the forepart of the instep to the back of the heel, thisart being occupied by a plate, or fixture, of metal, which I denominatethe metallic shank, which laps over the rear end of the outsole and iscontinued back in one piece so as to form a portion of the heel.

In the accompanying drawing, A, A, is the metallic shank which vis to becast of brass, or other metal, in one piece with the heel part D, D. Theleather outsole B, extends back so as to pass under the fore end of themetallic shank, where it is ski'ved off so that the shank may lie snuglyupon it. The shank is to be nailed, or sprigged, down through theinsole, on to an iron last, in the manner of nailing, or springing,soles of leather. The heel part is cast hollow, and the rim D, is to befilled in with cork and leather, or with leather alone, so as to risefiusli with the edge of the rim D. Vithin this rim the heel part isnailed, or sprigged, down in the same 'way with the other parts of themetallic shank, the holes for which are, in part,seen atD. The pieces ofleather which form the face of the heel may be readily renewed at anytime; and they are firmly held in place without any other fastening, byinserting them within the rim, the cavity being larger at the bottomthan at the top. Sometimes, for the sake of lightness, I do not allowthe metallic plate at D', to cover the whole surface of the heel, butmerely have a projecting rim of suflicient width to receive the nails,or sprigs.

Then a new sole is required, the old one may be readily removed fromunder the fore end of the metallic shank by forcing a suitableinstrument in between the leather and the shank, and removing the oldnails, or sprigs.

The cost of a pair of boots, or sho-es, of this kind will be but littlemore than ordinary, and they may be repaired with much greater facility,and will be considerably more durable.

YWhat I claim as constituting my invention, and desire to secure byLet-ters Patent, 1s

The employment of a metallic shank eX- tending along the instep and heelof boots and shoes, in place of the outsole of leather, said shank beingformed and affixed sub* stantially in the manner herein set forth.
